Thanks Mike.  That all sounds great.  Paramiko certainly looks like a 
good choice.

Python 2.6 might limit somewhat.  I'll have to see how far back in 
distros we could possibly go using 2.6.

When I get some time here I'll start playing around with these scripts.  
If at all possible I would prefer to use python over perl.  Better 
performance and little nicer syntax.
